Can you try unchecking the 'Request Exclusive access' option in the serial settings?

There is this long-standing issue with certain printers, and over the last 2 and a bit years I have maintained this plugin I've had 3 (now 4) reports of this issue. You can see one of them here where I also describe another workaround - #113.

I'm not sure how to fix it, as I have not yet found anything I can do differently with the effect process that will stop it inheriting the serial port as well. I can't reproduce the issue to work out exactly what is going on, these are just suspicions.

I will try that and report back. So far is the issue intermitent.

Thanks for your advice. Your suggestion - unchecking exclusive access has solved the issue.

Hi, I have the same problem, plugin WS2812 and Prusa i3 MK3S+. After uncheck "Request exclusive access to the serial port" the problem does not occur.
